    <p>I have created a database of users in my Ruby on Rails app, and now I'm trying to create a mailer that send emails to all users in my database whenever I want.</p> <p>Here's my model:</p> <pre><code>class MailMessage &lt; ActionMailer::Base def contact(recipient, subject, message) # host = Hobo::Controller.request_host # app_name = Hobo::Controller.app_name || host @subject = subject # @body = { :user =&gt; user, :host =&gt; host, :app_name =&gt; app_name } @body["title"] = 'This is title' @body["email"] = 'mark@doc.org.uk' @body["message"] = message @recipients = recipient @from = 'no-reply@doc.org.uk' @sent_on = Time.now @headers = {} end end </code></pre> <p>Here's my controller:</p> <pre><code>class MailMessageController &lt; ApplicationController def sendmail email = @params["email"] recipient = email["recipient"] subject = email["subject"] message = email["message"] MailMessage.deliver_contact(recipient, subject, message) return if request.xhr? render :text =&gt; 'Message sent successfully' end def index render :file =&gt; 'app/views/mail_message/index.html' end end </code></pre> <p>Here's my <code>views/mail_message</code>:</p> <pre><code>&lt;h1&gt;Send Email&lt;/h1&gt; &lt;%= form_tag :action =&gt; 'sendmail' %&gt; &lt;p&gt; &lt;label for="email_subject"&gt;Subject&lt;/label&gt; &lt;%= text_field 'email', 'subject' %&gt; &lt;/p&gt; &lt;p&gt; &lt;label for="email_recipient"&gt;Recipient&lt;/label&gt; &lt;%= text_field 'email', 'recipient' %&gt; &lt;/p&gt; &lt;p&gt; &lt;label for="email_message"&gt;Message&lt;/label&gt; &lt;%= text_area 'email', 'message' %&gt; &lt;/p&gt; &lt;%= submit_tag "Send" %&gt; &lt;%= form_tag %&gt; </code></pre> <p>Here's my <code>enviroment.rb</code>:</p> <pre><code>ActionMailer::Base.delivery_method = :sendmail ActionMailer::Base.sendmail_settings = { :location =&gt; '/usr/sbin/sendmail', :arguments =&gt; '-i -t' } ActionMailer::Base.perform_deliveries = true # the "deliver_*" methods are available ActionMailer::Base.raise_delivery_errors = true ActionMailer::Base.default_charset = "utf-8" ActionMailer::Base.default_content_type = "text/html" # default: "text/plain" ActionMailer::Base.default_mime_version = "1.0" ActionMailer::Base.default_implicit_parts_order = [ "text/html", "text/plain"] </code></pre> <p>When I run a test message, I get the following error:</p> <pre><code>You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.[] app/controllers/mail_message_controller.rb:4:in `sendmail' </code></pre> <p>It doesn't seem to recognise <code>sendmail</code>, but I have given its location. Any clues for how to fix this error will be very appreciated.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
